Abstract (en)
[origin: EP0609601A2] A contacts material (13a,13b) for vacuum valve (1) including an arc-resistant or arc-proof constituent having at least one of: tantalum, niobium, tungsten and molybdenum and an auxiliary constituent having at least one of: chromium, titanium, yttrium, zirconium, cobalt and vanadium. The contact material further includes a conductive constituent comprising: copper and/or silver. The amount of the arc-resistant or arc-proof constituent is from 25% to 75% by volume, the total amount of the arc-resistant or arc-proof constituent together with the auxiliary constituent being no more than 75% by volume, the conductive constituent forming the balance. The material leads to decreased restriking occurrence. <IMAGE>
